Seems like the 5d III is in your budget, available, and does what you want pretty much. AF in video is improved over the 7d but not great. No Wifi, but you can buy a WiFi card. Even has dual card slots so you put Wifi in one all the time.

Do you need the 10 FPS of the upcoming 7dII? The AF of the 5d III works great. I'm at a 99% keeper rate for AF - that's really good.

It doesn't make any sense. The poster of the OP ignores everything about the 5DIII and keeps banging on about a type of weather sealing on the 7D that doesn't exist. I don't think they are really interested in hearing the 7D does not have 1DX type environmental seals, nor that the 5DmkIII is equal to the 7D.
